Example:
blurAmount := 0.5 blurFormat := imaging.JPEG blurImage, err := Blur(imageBytes, blurAmount, blurFormat)
Parameters:
- content: the input image as a byte slice.
- blur: the amount to blur the image by.
- format: the format of the output image.
Returns:
- []byte: the blurred image as a byte slice.
- error: an error if the image could not be decoded or encoded.
